Job Summary:

The Senior System Integration & Optical Validation Engineer is responsible for leading the integration, system-level verification and validation (IV&V), and operational readiness of complex photonic quantum computing systems. This role develops integration strategies, test methodologies, validation processes, and deployment procedures to ensure integrated systems meet performance, reliability, and operational requirements.

Responsibilities:
  • Lead the integration, bring-up, verification, and validation of complex photonic, optical, electro-optical, and electronic subsystems for photonic quantum computing platforms.
  • Define and lead system-level integration and test strategies, including the design of experiments, to verify functionality, performance, and readiness of integrated systems using classical optical methodologies.
  • Develop system acceptance criteria, verification methodologies, commissioning processes, and validation roadmaps to enable consistent, repeatable deployment and product maturation.
  • Drive root-cause investigations and technical problem resolution through structured experimental methods, data-driven analysis, and close collaboration across Optical, Quantum, Electronics, Controls, and Test Engineering teams.
  • Own the development and continuous improvement of system integration and test infrastructure, including automation, laboratory instrumentation, engineering documentation, and scalable validation processes to improve efficiency, scalability, and system reliability.
  • Lead system installation, integration, bring-up, and operational readiness activities, including planning, execution, reporting, and technical training of engineering and operations personnel.
  • Provide technical leadership by establishing system integration and optical validation best practices and influencing system architecture to improve testability, deployability, manufacturability, reliability, and serviceability.
  • Mentor and develop engineers and technicians while fostering engineering excellence and cross-functional collaboration.

Experience/Qualifications:
  • M.S. or Ph.D. in Optical Engineering, Electrical Engineering, Photonics, Physics, or a related technical field with 5+ years of relevant industry experience, or B.S. with 10+ years of equivalent experience.
  • Extensive experience integrating, validating, and deploying complex optical, photonic, or electro-optical systems, including the specification, selection, qualification, and application of laboratory instrumentation and optical test equipment.
  • Demonstrated expertise in developing system-level test strategies, verification methodologies, acceptance criteria, and experimental approaches for complex integrated systems.
  • Strong understanding of optical technologies, including lasers, fiber optics, photonic components, optical instrumentation, and measurement techniques.
  • Proven ability to troubleshoot multidisciplinary optical systems using structured experimental methods, quantitative data analysis, and systematic root-cause investigation.
  • Experience developing automated test software, instrumentation control software, and engineering tools using Python or similar programming languages, with knowledge of Design of Experiments (DOE) and statistical data analysis.
  • Strong analytical, communication, and cross-functional collaboration skills, with the ability to make sound technical decisions in fast-paced engineering environments.
  • Experience with cryogenic systems or quantum technologies is highly desirable.
